Read his entire address to the Canon Law Association of Slovakia. He makes the point that aggressive secularization is converging in both the US & Europe and while it sounds right in a diverse society, it's a flawed model for at least two reasons. First:

“freedom of worship” is not at all the same thing as “freedom of religion.” Religious freedom includes the right to preach, teach, assemble, organize, and to engage society and its issues publicly, both as individuals and joined together as communities of faith. This is the classic understanding of a citizen’s right to the “free exercise” of his or her religion in the First Amendment to the U.S. Constitution. It’s also clearly implied in Article 18 of the Universal Declaration of Human Rights. In contrast, freedom of worship is a much smaller and more restrictive idea.

Second: how does this play out in real life? Are religious people actually free?

In the United States, a nation that is still 80 percent Christian with a high degree of religious practice, government agencies now increasingly seek to dictate how Church ministries should operate, and to force them into practices that would destroy their Catholic identity. Efforts have been made to discourage or criminalize the expression of certain Catholic beliefs as “hate speech.” Our courts and legislatures now routinely take actions that undermine marriage and family life, and seek to scrub our public life of Christian symbolism and signs of influence.
In Europe, we see similar trends, although marked by a more open contempt for Christianity. Church leaders have been reviled in the media and even in the courts for simply expressing Catholic teaching. Some years ago, as many of you may recall, one of the leading Catholic politicians of our generation, Rocco Buttiglione, was denied a leadership post in the European Union because of his Catholic beliefs.
Earlier this summer we witnessed the kind of vindictive thuggery not seen on this continent since the days of Nazi and Soviet police methods: the Archbishop’s palace in Brussels raided by agents; bishops detained and interrogated for nine hours without due process; their private computers, cell phones, and files seized. Even the graves of the Church’s dead were violated in the raid. For most Americans, this sort of calculated, public humiliation of religious leaders would be an outrage and an abuse of state power. And this is not because of the virtues or the sins of any specific religious leaders involved, since we all have a duty to obey just laws. Rather, it’s an outrage because the civil authority, by its harshness, shows contempt for the beliefs and the believers whom the leaders represent.

Not so much:

These events suggest an emerging, systematic discrimination against the Church that now seems inevitable.

Here we go again, though the last batch of atheistic ideologues were, you know, a bit gauche.

Today’s secularizers have learned from the past. They are more adroit in their bigotry; more elegant in their public relations; more intelligent in their work to exclude the Church and individual believers from influencing the moral life of society. Over the next several decades, Christianity will become a faith that can speak in the public square less and less freely. A society where faith is prevented from vigorous public expression is a society that has fashioned the state into an idol. And when the state becomes an idol, men and women become the sacrificial offering.

Our societies in the West are Christian by birth, and their survival depends on the endurance of Christian values. Our core principles and political institutions are based, in large measure, on the morality of the Gospel and the Christian vision of man and government. We are talking here not only about Christian theology or religious ideas. We are talking about the moorings of our societies -- representative government and the separation of powers; freedom of religion and conscience; and most importantly, the dignity of the human person.
This truth about the essential unity of the West has a corollary, as Bonhoeffer also observed: Take away Christ and you remove the only reliable foundation for our values, institutions and way of life.
That means we cannot dispense with our history out of some superficial concern over offending our non-Christian neighbors. Notwithstanding the chatter of the “new atheists,” there is no risk that Christianity will ever be forced upon people anywhere in the West. The only “confessional states” in the world today are those ruled by Islamist or atheist dictatorships -- regimes that have rejected the Christian West’s belief in individual rights and the balance of powers.
I would argue that the defense of Western ideals is the only protection that we and our neighbors have against a descent into new forms of repression -- whether it might be at the hands of extremist Islam or secularist technocrats.
